Thank you, Veikko! On both counts--for the compliment and for adding me
to
the Meteoptic links!

The subtle difference between cloudbow and fogbow is the size of the water
droplets. Technically, you and Mr. Greenler are correct because a fogbow
actually has the smaller water droplets, therefore less color. I see that
I
will have to correct the description on my home page!
My original source of information about cloudbows and fogbows was "The
Audubon Society Field Guide to North American Weather". In it, cloudbow
and
fogbow are described as being two words for the same thing. Another source
I
located
<at URL http://spot.colorado.edu/~sps/pasttriv/answer6.htm>
is where I learned about the size of the water droplets. Upon re-reading
it,
it does appear that I reversed the information about cloudbows and
fogbows.
It may have been unconsciously intentional because I like the sound of the
name "cloudbow" better than "fogbow"!

Sounds just BEAUTIFUL! Yes, I would think that the second sighting, with
the colors around the edges of the bright white, would be called a
cloudbow.

I'd love to see them!! Let me know if you put them on the Web.
Ciao!
